I am a buyer of body building vitamins, supplements, and steroid alternatives that help promote muscle growth. I am looking to find a Chinese supplier that can duplicate the body building vitamins that i currently sell at a lower cost. I can supply the products to you for your chemical analysis so that you can replicate them. You should be able to supply packaging as well. All packaging and labeling must meet USA labeling and packaging requirements so they can be imported into the USA.  If your company can produce these products, i am interested in hearing from you.
